Patent CA-1340001-C (CA)
Inventor: CHOE JUNG SOO
IPC: C01B23/00
Filed: 1987-10-27
Granted: 1998-08-18
Abstract: The present invention is a process for separating and recovering a component from a multi-component feed gas mixture.  The feed gas mixture is initially separated in a membrane separation unit or units to produce a gas stream concentrated in the desired component.  The concentrated gas stream is subsequently further separated in an adsorption unit having an adsorbent which selectively adsorbs non-desired gaseous components thereby producing a purified product stream.  The non-desired gaseous components are subsequently desorbed and a purge stream from the adsorption unit containing the desorbed non-desired gaseous components along with a portion of the desired components is recycled to the feed gas mixture.

Title: Saw chain for a motor-driven chain saw
Inventor: FISCHER MANFRED
IPC: B27B33/14
Filed: 1987-11-09
Granted: 1991-08-13
Abstract: Abstract of the Disclosure With motor-driven chain saws, there is the danger that the chain saw will be thrown upwardly and rearwardly when it is applied to wood by the user with a forward thrust.  Serious injuries can then occur.  The invention is directed to a saw chain which is so configured that the cutting forces are automatically reduced in response to the occurrence of excessive reaction forces so that the reaction force is immediately reduced to a tolerable amount thereby eliminating the kickback effect.  The drive links of the saw chain which engage into the nose sprocket of the guide bar are so dimensioned that they can further pivot in the tooth gaps of the nose sprocket out  of their normal position and, in this way,  take the cutting links with them in such a manner that the free angle .alpha. of the cutting teeth is reduced.

Title: Power control for cooking appliance with transient operating modes

Abstract: IMPROVED POWER CONTROL FOR COOKING APPLIANCE          WITH TRANSIENT OPERATING MODES                             ABSTRACT     A power control system for operating a heating element in a cooking appliance in response to the selection of one of a plurality of user selectable power settings. Approximate heating element temperature information is provided by a heater energy counter.  Each power setting has associated with it a corresponding steady state power level and a corresponding predetermined steady state energy count.  The steady state energy count is approximately proportional to the steady state operating temperature of the heating element when operated at its corresponding steady state power level.  The energy counter is selectively incremented and decremented to approximately track the beating element temperature when the count is respectively less than or greater than the steady state count for the applied power level.  At least certain ones of the power settings have corresponding minimum threshold counts less than the steady state counts and maximum threshold counts greater than the steady state counts.  To provide quick response to changes in power setting, the heating element is operated at a power level higher than that corresponding to the selected power setting whenever the heater energy count is less than its minimum threshold count and at a power level less than the power level corresponding to its selected power setting whenever the heater energy count is greater than its maximum threshold count.

Abstract: ABSTRACT         An expansion dowel assembly includes an axially extending anchor bolt and an expansion sleeve laterally enclosing the bolt.  At its leading end, the anchor bolt has an expansion cone displaceable opposite to the insertion direction of the dowel assembly relative to a conically-shaped expansion region at the leading end of the sleeve.  Initially, the cone angle of the expansion cone is larger than the cone angle of the expansion region of the sleeve.          A circumferentially extending annular bead is located on the outer circumferential periphery of the expansion region.  The expansion region is slotted in the axial direction and its wall thickness decreases in the circumferential direction toward the slots.  At the outset of the sleeve expansion, it is greatly widened and the annular bead is pressed into the surface of the borehole in which the dowel assembly is inserted.          As a result, a positive locking engagement is provided between the expansion sleeve and the receiving material in which the borehole is formed, so that the dowel assembly can be utilized in a cracked-prone tensile zone of the receiving material.
